Answers & Comments
1. radio waves, microwaves, infrared, visible light, ultraviolet, x-ray, gamma ray
2. transfer energy from one place to another, can be reflected, can be refracted
3. any electromagnetic wave's frequency multiplied by its wavelength equals the speed of light.
4. as the frequency increases. the wavelength gets shorter. as the frequency decreases, the wavelength gets longer.
5. the higher the frequency, the more energy, and the higher the amplitude, the more energy.
6. visible light waves are the only electromagnetic waves we can see.
7. three colors; red, green, and blue light
8. the color components of visible light include violet, blue, green, yellow to orange, bright red, and dark red.
hope it helps!
